Program Description

The Environmental Engineering (ENEN) Program emphasizes research in water resources and environmental engineering. Environmental engineers identify and design solutions for environmental problems, such as providing safe drinking water, treating and safely disposing of wastes, controlling water pollution, maintaining air quality and remediating contaminated sites. Water resources engineering is a profession that deals with the use, management and conservation of natural water resources above and below ground surface to assure availability and affordability of safe and clean sources of water for society. An individual plan of graduate study in environmental engineering compatible with a student’s interests and background is offered.

Program Specialties

The admission requirements and procedures correspond to the requirements set forth by the University of Maryland, Baltimore. Opportunities are available for undergraduate students to enroll in ENCE M.S. program as part of their home department's B.S./M.S. program.

Degree Requirements

The M.S. program is intended to provide an intensive education in both fundamental and applied aspects of environmental engineering. The student may choose a thesis or non-thesis option. The M.S. thesis option requires a minimum of 24 credit hours of coursework, plus six credit hours of research culminating in an acceptable and defensible thesis. The M.S. non-thesis requires a minimum of 30 credit hours of graduate course work plus three credit hours of research, resulting in an acceptable written scholarly report.

Ph.D. in Environmental Engineering

The Ph.D. degree has a greater emphasis on research compared with the M.S. degree and is geared toward successfully mastering a body of skills and knowledge in preparation for a career as an independent scholar. This degree is recommended for those who expect to engage in a professional career in research, teaching or technical work of an advanced nature. The basic requirements for the Ph.D. degree are the completion of a minimum of 30 credit hours of graduate courses beyond the bachelor’s degree (excluding graduate seminar and doctoral dissertation research credits), a minimum of 12 credit hours of ENCE 899 (doctoral dissertation research), passing a qualifying exam, successful preparation and defense of a dissertation proposal, and public defense of the doctoral dissertation. Course credit hours from the M.S. degree may be applied to the requirement of 30 course credit hours with approval from the student’s committee. Specific course work is determined by the candidate's Ph.D. committee based on the student's academic background and research topic.

All Ph.D. candidates are required to pass a written qualifying examination. The examination is given annually, and the student has two opportunities to pass. Additional requirements are imposed by the Graduate School.

Facilities and Special Resources

The program's research facilities include state-of-the-art laboratories at the Technology Research Center. Major analytical instrumental includes an Inductively coupled Plasma Mass Spectrometer, an Ion Chromatograph Mass Spectrometer, an Agilent 6890 gas chromatograph with a 5973 Network Mass Selective Detector capable of both electron impact and chemical ionization; two additional Agilent 6890 Gas Chromatographs, a Perkin-Elmer atomic absorption spectrophotometer with a graphite furnace; a DIONEX ion chromatograph; and a Total Organic Carbon analyzer. Additional equipment includes a centrifuge, analytical balances, meters (pH, specifc ion probes, DO, conductivity, turbidity, COD), shaking tables, centrifuge, refrigerators, vacuum pumps, drying ovens, a UV-VIS spectrophotometer, microscopes, muffe furnaces and a computer- controlled titrator. A reverse osmosis water source and autoclave are also available. ENCE facilities also house extensive treatability equipment. Computer labs are equipped with PCs and a dedicated server for data acquisition, analysis, modeling and simulation.

ENCE is co-located with the Center for Urban Environmental Research and Education (CUERE), the field offices of the NSF-funded Baltimore Ecosystem Study (BES) and related USDA Forest Service personnel in the Technology Research Center. CUERE’s mission is to advance the understanding of the environmental, social and economic consequences of changes to the urban and suburban landscape. CUERE and the BES jointly house a Spatial Analysis Laboratory and multiple wet laboratories for water quality, soil and sediment analysis. The Spatial Analysis Laboratory equipment includes high-end servers, storage devices, GIS workstations, one large-format plotter and one large-format scanner all linked with a high speed network. The lab holds licenses to the full suite of ESRI spatial analysis software, as well as specialized software for image analysis and LIDAR point classification and analysis.

UMBC is conveniently located with respect to a variety of terrestrial, fresh water and marine/estuarine habitats and is near a large number of private, state and national research institutions, including the Smithsonian Environmental Research Center, USDA Agricultural Research Service laboratories, the NASA Goddard Space Flight Center and the EPA Mid-Atlantic Assessment Program. The MD-DE-DC District Office of the U.S. Geological Survey Water Resources Division moved to the UMBC campus in 2007 under a federal cooperative agreement. The Center of Marine Biotechnology of the Maryland Biotechnology Institute is located eight miles from UMBC in downtown Baltimore. ENCE core faculty are appointed as faculty in the University System of Maryland Marine, Estuarine and Environmental Science (MEES) Program.

Research Design for the Urban Environment [3]
This is a core course in the IGERT "Water in the Urban Environment" program. Topics include the following: What are the valid and feasible research questions for different kinds of projects? What are the assumptions, conceptual models and research approaches associated with different disciplinary perspectives? What are the key requirements for successful interdisciplinary research? What themes and trends will be important in the near future in interdisciplinary environmental research focusing on urban environment and water resources? Students will work individually and as members of interdisciplinary teams to present case studies, analyze journal articles and grant proposals, educate other students about their own disciplinary perspective, terminology, and methods, and develop research plans in response to an example RFP addressing an urban water-related problem. Each team will prepare written documents and will present and defend its work to the faculty and other IGERT students.

ENCE 658
